This workpackage focuses on building a largely scalable middleware that will achieve unsupervised operation at 100+ sites. The main focus will be on attaining large scalability by exploiting the infrastructure provided by WP3. Parallel data streaming operators will be developed amenable to be deployed in large clusters to attain a large degree of scalability. Additionally, the platform will be autonomic supporting the following self-* properties:

Self-configuration and self-optimization: being able to redistribute components (and the associated load) whilst guaranteeing consistency and continuous operation.

Self-healing, tolerating failures and repairing itself without disruption processing what implies being able to recover sites without stopping processing (online recovery).

Self-provisioning, for allocating more or less sites depending on the required processing power by the current load.
